D, when a moving car suddenly stops, your body is still moving forward until the seatbelt stops you.
When things move, there is always friction. It's what makes cars move in the first place. The inside of the car doesn't move, however the wheels on the car are moving at a rapid pace. When the car stops violently, everything inside the car is thrown. The seat belt acts as a safety precaution if an accident happens.

Answer:
Oil : about 50years
Gas: about 52years
Coal: about 114years
Explanation:
Oil
Globally, we currently consume the equivalent of over 11 billion tonnes of oil from fossil fuels every year. Crude oil reserves are vanishing at a rate of more than 4 billion tonnes a year, so if we carry on as we are, our known oil deposits could run out in just about 50 years.
Gas
If we increase gas production to fill the energy gap left by oil, our known gas reserves only give us just 52 years left.
Coal
Although it’s often claimed that we have enough coal to last hundreds of years, this doesn’t take into account the need for increased production if we run out of oil and gas.
If we step up production to make up for depleted oil and gas reserves, our known coal deposits could be gone in 114 years.
